About

Hsuan Chang is a pioneering researcher in the fields of design for maintainability and virtual prototyping, with a focus on integrating motion planning into engineering design. His most influential work, "Assembly maintainability study with motion planning" (2002), has garnered 130 citations and addresses a long-standing challenge: automating the labor-intensive process of evaluating whether parts in an assembly can be accessed for routine maintenance. By applying constrained motion planning algorithms to CAD models, Chang transformed what was once a manual, physical-mockup-dependent task into a computational, virtual process. His research demonstrates how motion planning can enhance virtual prototyping, enabling earlier product introduction, higher quality, and lower costs. Chang's contributions are foundational to the development of digital tools that allow engineers to assess serviceability and assembly feasibility without physical prototypes. His work, including earlier studies like "Design for Maintenance by Constrained Motion Planning" (1995), has had a lasting impact on design automation and continues to influence modern approaches to maintainability analysis in product development.
